Factoring trinomials 3x^3-24x^2+45x​
yarga [219]

Answer:

Option B: 3x(x - 3)(x - 5)

Step-by-step explanation:

The given polynomial is: 3x³ - 24x² + 45x

To factorize it: 3x³ - 24x² + 45x

Since, 3x is common through out we can take it out.

⇒               3x(x² - 8x + 15)

Now we have to factorize (x² - 8x + 15)

The roots of this quadratic equation is: 5, 3.

Therefore, x² - 8x + 15 = (x - 3)(x - 5)

Combining them, the factors of the polynomial would be:

(B)                                     3x(x - 3)(x - 5)

How to Factor the Trinomial x^2 - x + 1 using the box method?<br><br><img src="https://tex.z-dn.net/?f=x%5E2%20-%20x%20%2B%201"
IRINA_888 [86]

Answer:

x = 1+√3 i/2 and x = 1-√3 i/2

Step-by-step explanation:

Given the expression x^2 - x+ 1, we are to factorize the expression as shown;

x^2 - x+ 1,

using the general formula

x = -(-1)±√1²-4(1)/2(1)

x = 1±√1-4/2

x= 1±√-3/2

x = 1±√3 i/2

Hence the required value of x are x = 1+√3 i/2 and x = 1-√3 i/2
